目的:探讨板层角膜移植术对带状角膜病变的治疗效果。方法:2003-01/2008-01我院角膜病组收治带状角膜病变患者16例(16眼)。其中男12例(12眼),女4例(4眼),年龄20～55岁,病史3～20a,患眼视力为光感～0.1不等。手术方法:根据病变的范围,选择不同直径环钻切除病灶,10-0的尼龙线间断缝合等大的植片和植床。结果:术后1wk内,植片可轻度水肿,之后渐变清亮,术后观察6mo～5a,未见病变复发及发生排斥反应者。术后视力均有明显提高,术后6mo,视力≥0.5者3眼,0.1～0.5者11眼,指数～0.1者2眼。结论:板层角膜移植术可以控制带状角膜病变病情发展,提高患眼视力,远期疗效稳定,是治疗带状角膜病变安全有效的疗法。
Objective: To investigate the therapeutic effect of lamellar keratoplasty on zonal keratopathy. METHODS: From January 2003 to January 2008, 16 patients (16 eyes) with corneal keratopathy were treated in our hospital corneal disease group. Including 12 males (12 eyes), 4 females (4 eyes), aged 20 to 55 years old, with a history of 3 ~ 20a, with visual acuity ranging from 0.1 to 0.1. Surgical methods: According to the extent of the lesion, select the different diameter ring drill to remove the lesion, 10-0 nylon sutures and other large intermittent suture and implantation. Results: Within 1wk after operation, the implants could be slightly edematous, and then gradually became clear and clear. Postoperatively, 6mo ~ 5a were observed. No recurrence and rejection occurred. Postoperative visual acuity was significantly improved 6mo, visual acuity ≥ 0.5 in 3 eyes, 0.1 ~ 0.5 in 11 eyes, index ~ 0.1 in 2 eyes. CONCLUSION: Lamellar keratoplasty can control the development of keratopathy and improve the visual acuity of eye. It is a safe and effective therapy for treatment of keratopathy.
